Inner Thigh Stretch
The inner thigh has a number of long delicate muscles (5 in total) called the adductors. These muscles work at bringing your leg back inwards during sideward's movements such as hitting a tennis ball.
After your stretching, you should perform some simulated movements of the action your stretching for. For example, some side steps each side, getting progressively larger and faster in motion to simulate your tennis movement prior to your game.
The outer thigh and gluts (buttock) muscles, does the opposite action, in that it takes the leg outwards. A good warm up and stretch, followed by some simulated movements will greatly improve your muscles flexibility, and thus improve your game or physical activity.

Moderate Leg Over

2. Keeping your right leg straight, use your right arm to push down on the knee of the left leg, exhaling slowly as you stretch.
